INJECTION-LOCKED DIVIDER

摘要: 注入鎖相分頻器可在較低輸入信噪比下工作,這是其他分頻電路不能比擬的優(yōu)點。本文對注入鎖相分頻器作了以下工作:(1)給出了輸入信號含附加噪聲時注入鎖相分頻器的通用相位方程和等效模型;(2)研究了無噪聲條件下調相信號通過注鎖分頻器的特性及分頻器的同步帶寬;(3)討論了輸入附加噪聲對注鎖分頻器特性的影響。注鎖放大器是本文中n=1的特例,本文的結果也適用于注入鎖相放大器。Abstract: An injection-locked divider (ILD) can provide good synchronization at lower input signal to noise ratio, which is its advantage over other types of divider. The general expression of phase equation and equivalent model are presented for the ILD with an input additive noise. In the absence of noise the performance of the phase-modulated signal through the ILD and synchronous ranges of the ILD are given. The effects of the additive noise on the ILD are discussed. The injuction-locked amplifier (ILA) is only a particular case in which n=1, therefore the given results are applicable to the ILA.
